coma SHELLER.

Application filed December 1,1927. Serial No. 236,918.

My invention is concerned with corn shellers, and is designed to obviate the difficulty which has heretofore existed resulting fromthe tendency of the husks that may be in the corn to wrap about the shelling cylinder shaft as they and the cobs emerge from the concave. This wrapping is objectionable as tending to clog the machine and cause it to consume more power in'its operation. To remedy this difliculty, I locate on said cylinder shaft and extending outside of the concave casing, a fan-like structure rotating with the shaft and acting somewhat as a fan and somewhat as a beater to drive the materials emerging from the concave awa-v tangentially and thus prevent the husks from possibly winding on the shaft.

To illustrate my invention, I annex hereto a sheet of drawings in which the same reference characters are used to designate identical parts in all the figures, of which Figure -1 is an end elevation of a portion of the delivery end of the concave casing showing my invention applied thereto;

Figure 2 isa vertical sectional view on the line 2-2 of Fig. 1;

Figure 3 is a detailed perspective view of half of the beater structure; and

Figure 4 is a perspective view of the entire beater structure, which is shown as detached from the supporting shaft in both perspective views.

My invention is adapted to be applied to any ordinary corn sheller, in which the customary cylinder shaftlO, journaled in suitable bearings, has secured thereon the shelling cylinder 11 having the teeth 12 cooperating with the bars 13 forming the cus-,

tomary shelling concave, which bars are suitably supported in the casing 14. having the sheet metal delivery end 15. In the specific construction shown, the end casting 16 of the cylinder has the shearing tooth 17 secured thereto and cooperating with the adjacent edge of the casing 15 to shear 011' and prevent husks being caught in the outlet, the upper portion 18 of which, as seen in Figure 1, is shaped like a section of an annulus, while the lower circular extension 19 thereof is adapted to receive the disc 20 which carries the blades 21 constituting the operative portion of my invention. This disc and the blades are preferably composed of two castings, preferably symmetrical and identical, except that one of them is 24 of the hub casting which has the aperture 25 therein through which extends a short square headed bolt 26 which is threaded into the aperture 27 in the blade 21 of the other half so that the bolts 26 serve to secure the two halves together and at the same time clamp them securely on the shaft 10. The outer portion of the blade containing the threaded aperture 27 and the entire other blade are preferably slightly inclined from a radial line so as to strike the cobs and husks at an angle, tending to throw them more away from the center than would be the case if the blades were set radially.

The operation of the apparatus will be readily apparent, as with the cobs and husks emerging from the portion 18 of the outlet aperture, they will be struck by the rapidly rotating blades 21 and thrown forcibly toward the side of the casing, and thus the may be necessitated by the state of the prior art.

What I claim as my invention and desire to secure by Letters Patent of the United States, is--' 1. In a corn sheller, the combination with a casing having a shelling concave therein, of a shaft journaled in said casing having a shelling cylinder secured thereto and cooperating with the concave when the shaft is rotated, an outlet in said casing for the cobs and husks, and beater blades secured to the shaft outside of the concave casing, substantially as and for the purpose described.

2. In a corn sheller, the combination with a casing having a shelling concave therein, of a shaft journaled in saidcasing having a shelling cylinder secured thereto and c0 operating with the concave when the shaft is rotated, an outlet in said casing for the cobs and husks, a disc secured to said shaft extending through the lower circular extension of the outlet, and beater blades secured to the outer face of said disc, substantially as and for the purpose described.

3. In a corn sheller, the combination with a casing having a shelling concave therein, of a shaft journaled in said casing having a shelling cylinder secured thereto and cooperating with the concave when the shaft is rotated, an outlet in said casing for the cobs and husks, a disc composed of two halves bolted together and thereby clamped on the shaft and extending through the lower circular extension of said outlet, and heater blades secured to the outer face of the disc, substantially as and for the purpose described.

4. In a corn sheller, the combination with a casing having a shelling concave therein, of a shaft journaled in said casing having a shelling cylinder secured thereto and cooperating with the concave when the shaft is rotated, a-shearing tooth extending radially froin the delivery end of the cylinder and cooperating with the inner wall of the casing, a disc secured on said shaft eXtending through the lower circular extension of said outlet, and heater blades secured on the outer face of the disc, said disc having a recess in its periphery to accommodate the shearing tooth.

In Witness whereof, I have hereunto set my hand this 29th day of November, 1927.

ALBERT E. GILMAN.
